S/UNI-155-TETRA
Quad 155 Mbit/s ATM and Packet Over SONET/SDH Physical Layer Device
FEATURES
• Quad channel ATM and Packet over
SONET OC-3c (155 Mbit/s) PHY.
• Provides on-chip clock and data
recovery and clock synthe sis.
• Exceeds Bellcore-GR-253 jitter
requirements.
• Inserts and extracts ATM cells or POS
packets into/from SONET SPE.
• Filters and captures Automatic
Protection Switch byes (K1 and K2)
and detects APS byte failure.
• Detects signal degrade and signal
failure thresholds crossing alarms.
• Captures and debounces
synchronization status byte (S1).
• Extracts and inserts the 16- or 64-byte
section trace (J0) and path trace (J1)
messages.
• Extracts and inserts section/line data
communication channels (DCC).
BLOCK DIAGRAM
• Provides circuitry to meet holdover,
wander and long term stability.
• Provides a generic 8-bit
microprocessor interface for device
control and register access.
• Provides standard IEEE 1149.1 JTAG
test port for boundary scan.
ATM
• Implements the ATM Forum User
Network Interface Specification.
• Performs cell payload scrambling and
descrambling.
• Provides a UTOPIA Level 2-compliant
system interface.
• Provides synchronous 4-cell transmit
and receive FIFO buffers.
PACKET OVER SONET
• Generic design that supports packet
based protocols like PPP, HDLC and
Frame Relay.
• Implements the PPP over SONET/
SDH specification according to RFC
1619 and 1662 of the IETF.
• Performs flag sequence detection and
insertion.
• Performs CRC-CCITT and CRC-32
FCS generation and validation.
• Performs byte stuffing and destuffing.
• Checks for mi nimum and maximum
packet lengths.
PACKAGING
• Low power, 3.3 V CMOS technology.
• Packaged in a 304-pin Ball Grid Array
(BGA) package.
• Industrial temp. range (-40° to +85°C).
APPLICATIONS
• WAN and Edge ATM Switches
• Multiprotocol Switches
• Layer 3 Switches
• Routers, Packet Switches, and Hubs
